Structured film changes the direction of light. Define the structured face and rotation in the assembly drawing, then evaluate viewing direction, uniformity and image quality.
Define the cut outline, usable aperture, thickness, tabs, notches, corner radii and tolerances. Identify prism direction or transmission axis, structured/coated face, liner handling and a physical orientation datum. A 0° or 45° catalog reference must be tied to the drawing datum.
Use the material in a custom optical stack or evaluate it against the original film in an existing backlight. Review luminance, uniformity, viewing angle, polarization, color and temperature behavior. Repair acceptance is based on the assembled display and agreed requirements; a similar gauge or family name does not establish equivalence.
Start with the application and available space. Develop a drawing with custom dimensions and performance specifications, review the proposed configuration, and evaluate samples where needed. Record the approved drawing revision and acceptance criteria for the supplied part. Availability and final configuration are confirmed during quotation.
